Description

New adaptive active noise canceling system is proposed.This system is composed of two controllers:an adaptive feedforward controller and a feedback controller.The adaptive controller can generate an artificial signal as the secondary source by detecting the noise from the primary noise source to reduce the noise level at the observation point.Our proposed method is guaranteed using the model on the basis of the strictly positive real property.New scheme can adjust the coefficient parameters in the IIR adaptive controller structure keeping the stability.Numerically and experimentally obtained results exhibited significant improvement on convergency and stability of the adaptive control schemes.
